Question

A definition of a variable outside any function is called a

a) local function definition
b) global variable definition
c) global function header
d) global function definition

Answer 1

A variable defined outside of all functions is termed a global variable definition, which means it can be accessed from anywhere in the program.

Step-by-step explanation:

A definition of a variable outside any function is called a global variable definition. In programming, variables can be classified into two main types: global and local. A global variable is one that is defined outside of all functions and is accessible from any function within the program. This contrasts with local variables, which are defined within a function and can only be accessed within that function's scope. Therefore, option (b) 'global variable definition' accurately describes a variable defined outside any function.

SUM UP Points

• A variable defined outside of all functions is known as a global variable.
• Global variables can be accessed from any function in the program.
• Local variables, on the other hand, are confined to the function in which they are defined.
